Explanation:

I got that answer on my own not from the Question ;)

Final answer:

The third energy level in an atom, as described by quantum mechanics, contains three sublevels: the s, p, and d sublevels.

Explanation:

In the field of chemistry, the term energy level refers to the fixed amount of energy that a system described by quantum mechanics, such as a molecule, atom, electron, or nucleus, can have. Specifically, when we refer to the third energy level, we're talking about an energy state with the principal quantum number n=3.

For any energy level defined by the principal quantum number n, there are n sublevels. Therefore, in a third energy level (n=3), we have three sublevels. These would be the s, p, and d sublevels.

Bronze contains 90 to 95 percent copper and 5 to 10 percent tin. Because these percentages can vary, bronze is classified as(1) a compound (3) a mixture
(2) an element (4) a substance

Answers

Answer: a mixture.


Justification:

1) Pure substances have a definite chemical formula: the same kind of atoms with the same fixed ratios and chemical bonds. Therefore, the percents of each element do not varye.


2) Elements and compounds are pure substaces. For example, Fe, Mg, Ti, are elements, and CO₂, CO, H₂CO₃ are compounds. Each of them will have always the same kind of atoms, in the same ratio and with the same chemcial bonds. Therefore the percents of the elements do not varye.


3) Mixtures are formed by the physical combination (not chemical bonds) of different elements or compounds in variable proportions. As indicated, this describes the material bronze, in virtue of the variation of its composition. Other examples of mixtures are solutions (like brines), air, ocean water, and milk: different brines, different oceans and different milk have different contents of elements or compounds.

Answer:

(3) a mixture

Describe the difference between chronic and acute exposure.

Answers

"Radiation exposure might be short-term or long-lasting. First, think of a medical x-ray exposure where the time of exposure is short—the machine is on and off within a very short period of time. Or think about radioactive materials that naturally occur in our soils; they present us with small amounts of radiation exposure that occur over our lifetime. Depending on the source, time of an exposure can vary—in some cases, the time will be very short, seconds or less, and in other cases it will be occurring continuously over our lifetime. Keep in mind that being exposed to radiation in a short period of time or over a long period of time is no indication of the total radiation dose and, thus, the possible health effects that may occur."

Answer: chronic is long term and severe while acute lasts for a short amount of time.

The complete combustion of fossil fuels and refuse producesA) radon and carbon monoxide.
B) volatile organic compounds.
C) sulfuric acid and nitric acid.
D) carbon dioxide and water vapor.

Answers

Final Answer:

The complete combustion of fossil fuels and refuse produces D) carbon dioxide and water vapor.

Explanation:

Fossil fuels and refuse, when subjected to complete combustion in the presence of sufficient oxygen, undergo a chemical reaction. This reaction primarily produces carbon dioxide (CO2) and water vapor (H2O).

In summary, complete combustion of fossil fuels and refuse results in the production of carbon dioxide (CO2) and water vapor (H2O) as the primary products.

Final answer:

The complete combustion of fossil fuels and refuse produces carbon dioxide and water vapor.

Explanation:

The complete combustion of fossil fuels and refuse produces carbon dioxide and water vapor. During combustion, the carbon in fossil fuels and refuse combines with oxygen from the air, resulting in the production of carbon dioxide (CO2) as the primary product. Additionally, hydrogen in the fuels and refuse combines with oxygen to form water vapor (H2O). This process releases energy in the form of heat and light.

Which type of reaction is represented by the generic equation AB + CD mc002-1.jpg AD + CB?combustion

decomposition

single replacement

double replacement

Answers

Answer : Option D) Double replacement

Explanation : Double displacement or replacement reactions are those in which the two reactant molecules exchange the cations and anions between them and give a new product.

So, in this case when the reaction is AB + CD → AD + CB

Here, both the species of reactant compound molecule went replacement with the adjacent cation and anion group and formed a new compound or product. Therefore, this can be called as double replacement reaction.
The type of reaction is represented by the generic equation AB + CD -> AD + CB is double replacement. The rest of the choices do not answer the question above. 

Which equation represents a neutralization reaction? A. 4Fe(s) + 3O2(g) → 2Fe2O3(s) B. 2H2(g) + O2(g) → 2H2O() C. HNO3(aq) + KOH(aq) → KNO3(aq) + H2O() D. AgNO3(aq) + KCl(aq) → KNO3(aq) + AgCl(s)

Answers

Answer : The correct option is, (C)

Explanation :

A.4Fe(s)+3O_2(g)\rightarrow 2Fe_2O_3(s)

This is synthesis reaction in which the two or more reactant react to give a single product.

B.2H_2(g)+O_2(g)\rightarrow 2H_2O(l)

This is combination reaction in which the two reactants combine to form a single product.

C.HNO_3(aq)+KOH(aq)\rightarrow KNO_3(aq)+H_2O(l)

This is a neutralization reaction in which an acid react with a base to give a salt and water as a product.

D.AgNO_3(aq)+KCl(aq)\rightarrow KNO_3(aq)+AgCl(s)

This is a double displacement reaction in which the positive cation and negative anion of two reactants exchange their places to give two new products.

Hence, the reaction (C) is a neutralization reaction.
The equation represents a neutralization reaction is HNO3(aq) + KOH(aq) → KNO3(aq) + H2O(). The answer is letter C. A. 4Fe(s) + 3O2(g) → 2Fe2O3(s), 2H2(g) + O2(g) → 2H2O() and AgNO3(aq) + KCl(aq) → KNO3(aq) + AgCl(s) are not neutralization reaction.
